TERMS AND ACRONYMS

Common Terms & Acronyms

The promise of 5G is faster and more reliable communications. 5G opens doors to exciting new connections to Internet of Things (IoT) networks, autonomous driving, broadband wireless, and interruption-free video viewing. Whatever you develop 5G technology for, it will be imperative to understand design and test concepts and solutions across multiple dimensions. There are a lot of 5G terms and more on the way. We’ve got you covered – here’s a list of what’s out there today.

2G

Second-generation digital cellular networks used by mobile phones, designed as a replacement for analog first-generation radio (1G). Designed primarily for voice using digital standards.

3G

Third-generation wireless mobile telecommunications technology, required by International Mobile Telecommunications for the year 2000 (IMT-2000) standard from International Telecommunication Union (ITU) to support at least 200 kbps at peak rate. First mobile broadband utilizing IP protocols added text and image messaging to voice phone calls.

3GPP – 3rd Generation Partnership Project

A mobile communications industry collaboration that organizes the development and management of mobile communications standards. With respect to 5G, 3GPP is managing the evolving 5G standards.

4G

Fourth-generation mobile telecommunications technology, designed to succeed 3G. A mobile broadband standard designed to support an all Internet Protocol (IP) network for calls, video, data, and web access. The performance goals of 4G are 100 Mbps for high-speed mobile applications such as automobiles, and 1 Gbps for low-mobility use cases including pedestrians and fixed-location access.

5G

Fifth-generation of mobile telecommunications technology, required by International Mobile Telecommunications for the year 2020 (IMT-2020) standard to support an all Internet Protocol (IP) network. Supports faster data rates, higher connection density, and much lower latency.

AAT – Antenna array tool

Software tool for embedding antenna parameters and radiation patterns in test scenarios.

ACP – Adjacent channel power

The power contained in a frequency channel next to the specified channel.

ACPR – Adjacent channel power ratio The ratio of the power contained in a specified frequency channel bandwidth relative to the total carrier power.

ACLR – Adjacent channel leakage ratio

The ratio of the transmitted power on the assigned channel to the power received on the adjacent channel after passing through a root raised-cosine filter.

AM distortion

Undesirable distortion caused by amplitude variation in a communications system.
